One of the limitations of these types of models is that they cannot describe the "true" nature of the …

Introduction

WebParton distributions in impact parameter space, which are obtained by Fourier transforming GPDs, exhibit a significant deviation from axial symmetry when the target and/or quark are transversely polarized. Connections between this deformation and transverse single-spin asymmetries as well as with quark–gluon correlations are discussed. The sign of … WebDownload scientific diagram Left panel: The evolution of the twist-3 contribution to the longitudinal chiral odd structure function, h n L (x, Q 2 ) along with the corresponding twist-2 piece, h ... ohno artist
